So i attempted to push in the center contact and I'm not sure if it is supposed to move but it definitely did not. So i was unable to try that properly. Its surprising how hard it is to find something non-conductive.
I also tried a test with the tank screwed on just until i could feel it make contact. As expected it went in to protect mode. then i backed it off by 1/4 turns untill it would fire as expected. about a full turn later it fired but it was no longer in contact with the head and so did not produce any vapor and was also loose enough that it would begin to unthread itself if it were bouncing around in my pocket.
I suppose I'll have to consider it defective and see about getting a replacement.
Thanks for your help.
Edit:
So i was able to find something rigid enough to push the pin in and do a few more tests. I have some audio gear i use to test cables and so on and using a 1/4 plug basically wired to itself (with a little rubber tip i rigged up on the end) it just shows non when i press the pin. if i take the tip off and let it contact the sides it shows 0.0.
Also tested with a small section of fire which meteres out at a low resistence and did a circuit test on it and still comes up 0.0. So I'm fairly certain its a bum unit. Most likely a short inside that shows up with a completed external circuit.
